How do i do special right triangles

Make a triangle with a 90° angle

and another two angles at 45°angles

that's  how you make a special right triangles

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the correct answer is $7.38
